Using our knowledge of Latin roots, prefixes and suffixes can allow us to discover the meaning of unknown words when reading a text. In this case, if the prefix "in" means "not" and the word "sensus" means "to feel or perceive," then the word "insensibility" most likely means "unable to feel," and probably refers to someone who does not feel things very deeply.

True

Explanation:

Our language is very Latin-based and if we know the roots of Latin words, we will, in fact, be able to recognize the meaning of unknown words, along with the knowledge of suffixes and prefixes. With the mastery of this concept, it is entirely possible that we can understand the meaning of the word "insensitivity" which, according to the interpretation of prefixes, suffixes and Latin roots, means something "incapable of feeling". This word, in this case, can be used to describe someone who does not feel things deeply and emotionally, but it can also refer to a physical inability to feel.
